Secomp STANDARD USB Type-C to HDMI Adapter Cable S3731, USB-C to HDMI, 2 m

The Secomp STANDARD USB Type-C to HDMI Adapter Cable S3731 is a 2 m cable designed to convert a USB-C video output to an HDMI signal for connection to monitors, TVs and projectors. It carries both video and audio over a single cable, allowing devices with compatible USB-C video output—such as laptops, tablets and some smartphones—to display content on HDMI-equipped screens without requiring a separate dongle or power source.

Advantages

This USB-C to HDMI cable offers a compact single-cable solution that reduces clutter while providing reliable digital video and audio transmission. At 2 m length it gives flexible placement of source devices and displays. The cable is plug-and-play on systems that support USB-C video output, eliminating the need for software installation in most cases. Its fixed cable construction avoids an additional adapter component and simplifies connection and transport.

Suitable for

• Connecting a laptop with USB-C video output to an external monitor or TV for extended desktop or mirroring
• Presentations on projectors in meeting rooms and classrooms
• Streaming video and audio from tablets or phones to HDMI TVs
• Home office setups where a single cable between device and display is preferred

When it may not be suitable

This cable requires a source device that supports USB-C video output (DisplayPort Alternate Mode); it will not provide video from USB-C ports that support only charging or data transfer without video. It is not a multiport hub and does not add USB, Ethernet, or power-delivery functionality beyond the native capabilities of the connected devices.

Key specifications

• Connector types: USB Type-C (source) to HDMI (display)
• Cable length: 2 m
• Transmits digital video and audio over a single cable
• Supports typical HDMI display resolutions subject to device and display capabilities
• Plug-and-play operation on compatible devices

How to use

Connect the USB-C end of the cable to the source device’s USB-C port that supports video output, then plug the HDMI end into the display’s HDMI input. Select the correct HDMI input on the display. On some systems adjust display settings such as resolution, scaling or display mode (mirror/extend) in the operating system if necessary. No external power or drivers are normally required when the source device provides USB-C video output.

What to consider before purchase

• Verify that your device’s USB-C port supports video output (DisplayPort Alternate Mode)
• Check the HDMI input type and supported resolutions of your display to ensure compatibility
• Decide whether a fixed cable length of 2 m meets your placement needs

Usage recommendations

Use short, gentle bends and avoid kinking the cable to maintain signal integrity. If you encounter no video output, confirm the source device’s video over USB-C capability and try a different HDMI input or cable to isolate the issue.
